1565cbc65c lavfi: make avfilter_free() remove the filter from its graph. 2013-04-11 20:38:48 +02:00

bc1a985ba0 lavfi: replace avfilter_open() with avfilter_graph_alloc_filter(). 
Since we do not support "standalone" filters not attached to an
AVFilterGraph, we should not have a public function to create such
filters. In addition that function is horribly named, the action it does
cannot be possibly described as "opening" a filter.

7e350379f8 lavfi: switch to AVFrame. 
Deprecate AVFilterBuffer/AVFilterBufferRef and everything related to it
and use AVFrame instead.

565e4993c6 lavfi: merge start_frame/draw_slice/end_frame 
Any alleged performance benefits gained from the split are purely
mythological and do not justify added code complexity.

58b049f2fa lavfi: support automatically inserting the fifo filter when needed. 
This breaks libavfilter ABI.

9baeff9506 lavfi: replace AVFilterContext.input/output_count with nb_inputs/outputs 
This is more consistent with naming in the rest of Libav.

9d0bfc5052 lavfi: make AVFilterPad opaque after two major bumps. 
It will allow adding new fields to it without ABI breaks.

803391f719 lavfi: remove request/poll and drawing functions from public API on next bump 
They are only useful inside filters and we don't allow user filters for
now.

fa417fcd27 lavfi: make avfilter_insert_pad and pals private on next bump. 
They are only useful inside filters and we don't allow user filters for
now.

8eb9bf0933 avfiltergraph: make some functions static. 
They are not used outside of avfiltergraph.c

0b45334a58 lavfi: move audio-related functions to a separate file. 
This is easier to follow than having them randomly scattered in
avfilter.c and defaults.c.

eb7ccf8f33 Make the avfilter debug functions and macros static to avfilter.c 
This removes ff_get_ref_perms_string, ff_dprintf_ref and ff_dprintf_link
fro the interface of libavfilter.

4723bc2868 Make avfilter_default_free_buffer() an internal shared symbol, so that 
it can be referenced outside defaults.c.

4fcbb2af33 Prefix with "ff_" the functions: 
ff_avfilter_graph_check_validity()
ff_avfilter_graph_config_links()
ff_avfilter_graph_config_formats()

and move their declaration to internal.h. These functions are never
used in application code, so it is better to consider them internal
functions, this can be changed later if necessary. Simplify API.

b5fbb31e55 Rename ff_dprintf_picref() to ff_dprintf_ref(). 
The function is going to be used to represent also audio data.

ecc8dada37 Rename AVFilterPicRef to AVFilterBufferRef. 
The struct is going to be used for storing audio buffer references as
well, and the new name is more generic.

Patch by S.N. Hemanth Meenakshisundaram @smeenaks@ucsd@edu@.

9f0e31d29a Make avfilter.c dprintf* functions internal and declare them in an
